There are no compliance mechanisms under the London Convention, however, with the entry into force of the London Protocol on 26 March 2006, a set of Compliance Procedures and Mechanisms, pursuant to Article 11, were adopted in November 2007. It included the establishment of a subsidiary body - the Compliance Group - that meets in parallel to the Meeting of Contracting Parties and provides advice to the Parties on such matters. Further details are found in the document in the menu to the right.

The objective of the Compliance Procedures and Mechanisms under the London Protocol is to assess and promote compliance with the London Protocol with a view to allowing for the full and open exchange of information, in a constructive manner. The Meeting of Contracting Parties retains overall responsibility for compliance matters.
